Patent JP-H05102651-A (JP)
Title: Surface mounting method for circuit element
Inventor: KOYANAGI MASAYOSHI
IPC: H05K3/34
Filed: 1991-10-04
Abstract: PURPOSE:To provide a method for surface mounting a circuit element which prevents short-circuits between adjacent connecting pads on a board and the adjacent leads on the circuit element. CONSTITUTION:Cream solder is printed on a connecting pad formed on a board 1 and the lead 5 of a flat package type circuit element 4 is brought into contact with the connecting pad. When the cream solder on the board 1 is heated, the board 1 is mounted on a jig 6 and the melted cream solder is prevented from flowing into the adjacent connecting pad and the lead 5 by the dividing wall 10 of the jig 6. Thus, short-circuit of the adjacent connecting pad and the lead 5 is prevented by the solder. The relative deviation of the lead 6 of the circuit element 4 from the connecting pad of the board 1 is modified in a process before heating the cream solder.

Title: Electric wire holder for waterproof connector
Inventor: SAIJO EIJI
IPC: H01R13/58
Filed: 1993-09-20
Abstract: PURPOSE:To ensure a waterproofing function even in the case of bending an electric wire drawn out from the rear part of a waterproof connector. CONSTITUTION:An electric wire holder 8 is mounted to a position separated by a prescribed distance along an insulated wire 5 behind a rubber plug 7 and inserted to a wire insertion tube 2. In a condition thus obtained, when a free part 5b of the insulated wire 5 is laterally taken out, a bending position of the insulated wire 5 is restricted in a rear side of the rubber plug 7 by the wire holder 8, and since also bending force acts in only the wire holder 8, a linear part 5a is maintained almost in a linear shape, to prevent the bending force from acting in the rubber plug 7. Consequently, no clearance is generated between a through hole 11 of the rubber plug 7 and the insulated wire 5, and sure waterproofing can be performed by preventing water from infiltrating.

Title: Semiconductor element isolation method
Inventor: OSAWA TOMOKO
IPC: H01L21/76
Filed: 1990-09-27
Abstract: PURPOSE:To reduce stepped portions formed owing to an oxide film and hence prevent any disconnection at step from being produced serving in a wiring process by forming a slightly thicker oxide film serving to isolate elements and removing the top of the same to obtain an object value. CONSTITUTION:When a thermal oxide film 12 is formed to be thicker than an object film thickness B on a silicon substrate 5 with a nitride film 9 as a mask, thermal oxidation in the substrate 5 goes deeper than the case with the object film thickness B. Accordingly, provided an upper oxide film C is removed so as to provide the film thickness B, the oxide film 12 reduced in stepped portions corresponding to the extent of the thermal oxidation going deeper, and hence inconvenience such as step disconnection portions and the like in a wiring process can be prevented.

Title: Automobile clutch control device
Inventor: YANO MASAYA
IPC: B60W10/10
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To prevent an automatic clutch from being connected before the completion of shift even in a low temperature case of a transmission. SOLUTION: When the gear stage of a transmission is mechanically shifted according to the operation of a shift lever, gear-in (slightly before the completion of shift) is judged by the on→off change of a gear-in switch (S6), and an automatic clutch is then connected at specified timing (S11). When engine cooling water temperature Tw is lower than the specified temperature Tw* (about -10 deg.C--20 deg.C), that is, when lubricating oil in the transmission is low in temperature and high in viscosity, and it takes time before the completion of shift (YES in S9), delay processing is performed to delay connection timing of the automatic clutch (S10).

Title: Disk recording method
Inventor: ONO TSUYOSHI
IPC: G11B20/12
Filed: 1990-09-27
Abstract: PURPOSE:To maintain the quality of a reproducing sound by performing an encoding processing before starting an actual recording operation at least prior to a data of the longest delay amt. of an interleaving processing and starting the actual recording operation when a prescribed recording starting position is effected. CONSTITUTION:When a continuous music signal is distributed to plural recording means Ha and Hb and simultaneously recorded on a disk D, an area A of the disk D is recorded by the recording means Ha and an area B of the disk D by the recording means Hb respectively by moving the two recording means Ha and Hb in rotating the disk D by a spindle motor M. With regard to the recording means Hb as a later recording means in time series, the encoding processing is performed on recording to be retroactively effective more than the max. delay amt. due to the interleaving before the actual recording operation is started up, and a recording gate is opened at the time of reaching a connecting position of recording to start the actual recording operation. By this method, the occurrence of a null part due to delay of the interleaving processing is prevented, thus securing the continuity of data.

Title: Programmable read only memory
Inventor: MASUDA HAJIME
IPC: G11C17/18
Filed: 1988-10-13
Abstract: PURPOSE:To partly use a write current to a base current and to decrease the area occupied by an output stage transistor TR by securing such a constitution of a row selection circuit where the base current of the output stage TR is supplied from a row line via a diode and an amplifying TR in a write state. CONSTITUTION:In a write state the collector current of an output stage TR Q4 increases and reaches the VBE of the TR Q4, the VCE of an amplifying TR Q3, and the forward voltage VD of a diode D1. Thus a write current partly flows from a row line W through the D1. Therefore the size of the TR Q4 can be reduced and the values of resistances R1 and R2 can be increased. In a read state a TR Q2 selected by an address signal AD is turned on to supply the base current of the TR Q4. When the TR Q4 is turned on, the D1 is turned off. Then the base current of the TR Q4 is supplied via both R1 and R2. Thus the current consumption is reduced.

Abstract: PURPOSE:To obtain a thermal head of high accuracy with high yield, by a method wherein a heating layer and a first gold layer are formed on a substrate; the first gold layer is patterned, using this as a mask the heating resistor layer is patterned; a second gold layer is formed at least on the position having a feeder layer pattern in the first gold layer; and the gold layer formed on a heating part of the resistor layer is removed. CONSTITUTION:Under vacuum, a heating resistor layer 2 is formed on a substrate 1 of a glazed ceramic substrate etc. by sputtering and continuously a first Au layer 7 is film-formed. Using the first Au layer 7 pattern to a required shape as a mask, the heating resistor layer 2 is patterned to a required shape by dry etching using CF4 gas. After a resist is completely removed, a second Au layer 8 is pattern-deposited on the pattern of the first Au layer by electro- plating with gold. Thereafter, the first and second Au layers 7, 8 are removed only at the portion thereof over a heating part 2a of the heating resistor layer 2 by photolithoetching. A feeder layer (a) consists of the first and second Au layers 7, 8 remaining after removed.

Title: Monitoring unit of process state
Inventor: SHIBATA KOJI
IPC: G05D7/06
Filed: 1984-12-07
Abstract: PURPOSE:To attain the process control with reduced load of an operator and small number of errors by monitoring the transient and detecting a fault of a valve drive mechanism. CONSTITUTION:A change detecting means 4 always monitors all close and open signals applied to an input scan means 3 and checks whether all close signals have changes or not. When the changes are decided, it is decided whether all close signals are presently kept ON or OFF. If the present state is not fully close, it means that a valve starts opening. Therefore a valve open command signal is turned on without fail. Thus a fault state generation flag is set when it is confirmed that said command signal is kept ON. While the end of the valve closing operation is decided when the present state is fully close. Then a closing operation flag is cleared.
